Operator tells me the problem started when they put a new master roll in. Master removal fingers are not broken. Drum clamp operations are not stopping rotation. Checked all fuses. No rotation when sw on main board is pressed. Drum drive gears are in sync. I have fixed this model since it was first made never had this code that will not go way after drum rotation is made possible.
